emergency medical identification

cards, bracelets, or necklaces with a written message used by people with diabetes or other medical problems to alert others in case of a medical emergency such as a coma.

endogenous

grown or made inside the body. Insulin made by a person’s own pancreas is endogenous insulin. Insulin that is made from beef or pork pancreas or derived from bacteria is exogenous because it comes from outside the body and must be injected.

exogenous

grown or made outside the body; for instance, insulin made from pork or beef pancreas is exogenous insulin for people.

fatty acids

a basic unit of fats. When insulin levels are too low or there is not enough glucose (sugar) to use for energy, the body burns fatty acids for energy. The body then makes ketone bodies, waste products that cause the acid levels in the blood to become too high. This in turn may lead to ketoacidosis, a serious problem. See also: diabetic ketoacidosis.

fiber

a substance found in foods that comes from plants. Fiber helps in the digestive process and is thought to lower and help control blood glucose (sugar). The two types of fiber in food are soluble and insoluble. Soluble fiber, found in beans, fruits, and oat products, dissolves in water and is thought to help lower blood fats and blood glucose. Insoluble fiber, found in whole-grain products and vegetables, passes directly through the digestive system, helping to rid the body of waste products.

food exchange

See: exchange lists.

foot care

taking special steps to avoid foot problems such as sores, cuts, bunions, and calluses. Good care includes daily examination of the feet, toes, and toenails and choosing shoes and socks or stockings that fit well. People with diabetes have to take special care of their feet because nerve damage and reduced blood flow sometimes means they will have less feeling in their feet than normal. They may not notice cuts and other problems as soon as they should.

gene

a basic unit of heredity. Genes are made of DNA, a substance that tells cells what to do and when do do it. The information in the genes is passed from the parent to child-for example, a gene might tell some cells to make the hair red or the eyes brown.

genetic

relating to genes. See also: gene; heredity.

gestation

the length of a pregnancy.

glycemic response

the effect of different foods on blood glucose (sugar) levels over a period of time. Researchers have discovered that some kinds of foods may raise blood glucose levels more quickly than other foods containing the same amount of carbohydrates.

immunosuppressive drugs

drugs that block the body’s ability to fight infection or foreign substances that enter the body. A person receiving a kidney or pancreas transplant is given these drugs to stop the body from rejecting the new organ or tissue. Cyclosporin is a commonly used immunosuppressive drug.

insulin allergy

when a person’s body has an allergic or bad reaction to taking insulin made from pork or beef or from bacteria, or because the insulin is not exactly the same as human insulin or because it has impurities.

The allergy can be of two forms. Sometimes an area of skin becomes red and itchy around the place where the insulin is injected. This is called a local allergy.

In another form, a person’s whole body can have a bad reaction. This is called a systemic allergy. The person can have hives or red patches all over the body or may feel changes in the heart rate and in the rate of breathing. A doctor may treat this allergy by prescribing purified insulins or by desensitization.

insulin antagonist

something that opposes or fights the action of insulin. Insulin lowers the level of glucose (sugar) in the blood, whereas glucagon raises it; therefore, glucagon is an antagonist of insulin.

insulin binding

when insulin attaches itself to something else. This can occur in two ways. First, when a cell needs energy, insulin can bind with the outer part of the cell. The cell then can bring glucose (sugar) inside and use it for energy. With the help of insulin, the cell can do its work very well and very quickly. But sometimes the body acts against itself. In this second case, the insulin binds with the proteins that are supposed to protect the body from outside substances ( antibodies). If the insulin is an injected form of insulin and not made by the body, the body sees the insulin as an outside or “foreign” substance. When the injected insulin binds with the antibodies, it does not work as well as when it binds directly to the cell.

insulin-induced atrophy

small dents that form on the skin when a person keeps injecting a needle in the same spot. They are harmless. See also: injection site rotation.

intensive management

a form of treatment for insulin-dependent diabetes in which the main objective is to keep blood glucose (sugar) levels as close to the normal range as possible. The treatment consists of three or more insulin injections a day or use of an insulin pump; four or more blood glucose tests a day; adjustment of insulin, food intake, and activity levels based on blood glucose test results; dietary counseling; and management by a diabetes team. See also: team management.

intravenous injection

putting a fluid into a vein with a needle and syringe.

lactic acidosis

the buildup of lactic acid in the body. The cells make lactic acid when they use glucose (sugar) for energy. If too much lactic acid stays in the body, the balance tips and the person begins to feel ill. The signs of lactic acidosis are deep and rapid breathing, vomiting, and abdominal pain. Lactic acidosis may be caused by diabetic ketoacidosis or liver or kidney disease.

morbidity rate

the sickness rate; the number of people who are sick or have a disease compared with the number of people who are well.

one of the 17 institutes that make up the National Institutes of Health, an agency of the Public Health Service.

nutrition

pancreatitis

inflammation (pain, tenderness) of the pancreas; it can make the pancreas stop working. It is caused by drinking too much alcohol, by disease in the gallbladder, or by a virus.

peak action

polyunsaturated fats

a type of fat that comes from vegetables.

preeclampsia

a condition that some women with diabetes have during the late stages of pregnancy. Two signs of this condition are high blood pressure and swelling because the body cells are holding extra water.

shock

a severe condition that disturbs the body. A person with diabetes can go into shock when the level of blood glucose (sugar) drops suddenly. See also: insulin shock.

systemic

a word used to describe conditions that affect the entire body. Diabetes is a systemic disease because it involves many parts of the body such as the pancreas, eyes, kidneys, heart, and nerves.

toxemia of pregnancy

a condition in pregnant women in which poisons such as the body’s own waste products build up and may cause harm to both the mother and baby. The first signs of toxemia are swelling near the eyes and ankles (edema), headache, high blood pressure, and weight gain that the mother might confuse with the normal weight gain of being pregnant. The mother may have both glucose (sugar) and acetone in her urine. The mother should tell the doctor about these signs at once.

vaginitis

Type 1 diabetes develops most often in young people but can appear in adults.
